Bricklaying- 28 Jan 2025
I recently hired A1&PM to carry out structural repairs on my house, including replacing window lintels and providing complex temporary works to support the structure during the repairs. They also patched plaster, skimmed a wall, rendered, and repointed an external wall. From start to finish, the team was professional and reliable, turning up on time with all the necessary tools and materials. Protecting carpets and covering furniture. Their knowledge and expertise were evident throughout, and they completed the work exactly as promised. The pricing was very competitive, and the quality of the work exceeded my expectations. I was initially sceptical due to some past review, but my experience couldn't have been better. I would definitely use their services again and wouldn't hesitate to recommend them to others. Fantastic work—thank you!

Conversions - General- 21 Jun 2025
Working with Petrit was a very pleasant and enjoyable experience. He and his team are friendly and open for discussions. They’re quick, affordable, and help with decision making. Would hire again! Have to say as well, as a woman, Petrit and his team treated my husband and I equally, unlike my experience with other tradesmen who direct all their conversations to the men. Petrit knocked opened up our living kitchen area, laid herringbone floors, replastered the property, installed new radiators, added a built in ladder to our attic, and re did our bathroom. He also helped us match the floor boards from an existing room and helped us source front and back doors for much better price than what we were getting quoted in East London. The painting of the entire house was done in a rush as we needed to move in, so the attention to detail fell down a little here compared to everything else that was done, but I wouldn’t hesitate to work with Petrit again!! After and before pics included!

Extensions- 22 Dec 2022
Imran is a contractor who is personable and is trying hard, but at the end relies on different teams of builders to carry out the work. His knowledge of building work appears at time limited. In our case, this has often led to poor communication/hand-over, extensive delays and often poor (if not careless) craftsmanship. Very stressful. We now have builders (family business) finalising our project.

I had my double side and single rear L shape Extension which had kitchens and bathrooms with bedrooms. It was turnkey project and didn’t know them before but they are Pro Contractor as they got all planning permission approved with structural calculations. They completed work in time with high standard quality and regulations and got my certificates from council. I would recommend them as Pro builder all the time.

Extensions- 23 Aug 2023
On schedule and to budget, Ibrahim and his team from Triada Building Ltd delivered a very high standard on this project. Despite poor weather (Summer of 2023) and some issues with 3rd party contractors, access for concrete pour, skip delivery etc. his team worked each stage of the project to plan keeping me informed and showing great level of craftsmanship. I was after a simple workshop build that would compliment our house and he did not try to over sell options I wasn't interested in. Very happy with the result, and would recommend. Thank you.
